Bucket wheel excavators (BWE)
The Joint Stock Company UNEX has been manufacturing bucket wheel excavators for more than 50 years. So you can consider UNEX to be an experienced specialist in manufacturing of large-scale machinery for use in open pit-mines. The UNEX team of well-trained specialists is able and ready to react to all its customers’ individual requirements. More than 130 custom-built excavators and reclaimers can be found in e.g. Czech Republic, Russia and the Ukraine, in Bosnia and Herzegovina, Macedonia, Bulgaria, Poland and Slovakia.
There are two types of bucket wheel excavator: Compact and Classical. The division depends on the possibility of repeated assembly and disassembly.
1. It is not possible to assemble and disassemble the Classical BWE. The excavator moves on either a caterpillar or walking undercarriage. Their capacity ranges from 1 200 to 6 500 m3/h and the specific cutting force from 90 to 168 kN/m. According to the adjustable distance between the wheel and the axis of the machine, classical BWEs are divided into two groups: excavators with a telescopic bucket wheel boom (KU 300 and KU 800) and without a telescopic bucket wheel boom (K 2000).
2. The Compact BWE can be repeatedly assembled and disassembled. Their capacity ranges from 400 to 2 800 m3/h and the specific cutting force from 25 to 145 kN/m.

Drive it at highway speeds. Drive it from job to job. And drive it back to the safety of the equipment yard at night. It's an advantage that's made the Gradall wheeled undercarriage design famous throughout the world for over a half-century.
- Drive a Gradall excavator at speeds up to 55 mph.
- There's no need for a lowboy trailer; no unnecessary transport expense. And no lost time moving the machine to the job and back.
- Front axle lockout cylinders provide the Gradall with a stable working platform. There's no need for stabilizers.
- The Gradall undercarriage can be repositioned from the upperstructure operator cab using a speed selection switch in the cab. That saves time, makes repositioning more efficient and increases productivity.
- Choose a standard rear-wheel drive 6 x 4 or 4 x 2, or optional 6 x 6 or 4 x 4 capabilities, depending on your needs.

Bucket wheel and bucket chain excavators are important products designed for mining the overburden. The first bucket chain excavator of our own construction called D 800 was manufactured in 1952, with an output of 1 050 m3/h and moved on rails. The most effective bucket chain excavator is marked RK 5000 and it achieves an output of 5 000 m3/h of excavated overburden.
Our production range covers also the biggest digging wheel excavator of the Czech Republic, the K 10000, which has been working with an output of 10 000 m3/h of excavated overburden in Bílina mine since 1978.
Bucket-chain and bucket-wheel excavators are designed according to specific requests of customers, always with respect to the actual mining conditions in which they will operate.

Bucket Wheel Excavators (BWE) are continuous cutting machines for soft to semi hard materials like clay, sand, gravel, marl and their blendings as well as lignite and hard coal. Tenova TAKRAF Bucket Wheel Excavators excavate a wide range of capacities between 200 and 16000 m³/h and at working bench heights from less than 5 m to maximal 51 m.
The Bucket Wheel Excavator is favorable connected to a belt conveyor system with or without a Mobile Transfer Conveyor intermediately installed or a cross pit spreader transferring the material to the waste dump or the raw material stockpile.
According to local mine conditions Compact and Large Bucket Wheel Excavators are offered - whereas the selection mostly is determined by required cutting height and width (working block).
The characteristic parts of a Bucket Wheel Excavator are the cutting wheel with buckets, the wheel boom, the superstructure with counterweight boom, the substructure, the undercarriage with crawler tracks and a transfer boom to the bench conveyor (or a connecting bridge to the loading unit). All main parts are designed to meet the demands of the project regarding optimization, standardization and maintenance. Therefore, Tenova TAKRAF stands with more than 100 years of Bucket Wheel Excavator-experience.
Bucket Wheel Excavators are among the largest terrestrial vehicles ever constructed - the biggest machine built, the Tenova TAKRAF SRs 8000, has a weight of 14.200 t and moves 240,000 m³ of overburden per day.
